To all whom it may concern:

Be it known thahi, WILLIAM -H'. HART, Jr., a citizen of theUnited States, residing in the city and county of Philadelphia, State of Pennsylvania,'hav'e invented a new. and useful Mailing-Envelop, of which the following is a specification.

My invention consists ofya mailing envelop or package-composed of a body and a closing flap therefor, and an additional flap which is adapted to be connected with said closing flap and secured to said body, where by while the envelop may be held reliably in closed position, it may be opened to inspect the contents thereof without fracturing The inventionis satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, as long as they are includedin the scope of the claim.

Figure 1 represents a rear elevation of an envelop embodying my invention, the same being in closed condition. Fig. 2 represents a rear'elevation of a portion of the same in open condition. Fig. 3 represents a longitudinal section on the line mw Fig. 1. Fig. 1 represents a rear elevation of aportion of the envelop in closed condition. Figs. 5 and 6 represent elevations of detached members. Similar numerals of reference indicate correspondingparts in the figures.

Referring to the drawings, 1 designates an envelop composed of the body 2 and closing flap 3 therefor, the latter having a transversely-extending' slit or opening 4 therein.

7 5 designates a T-shaped tongue whose head is widerthan-said slit 4and whose main length 6 isadapted'to be passed through said slit so that when said head is on the inner face of said flap the shoulders 7 of the tongue abut against the walls of said slit 4 and overlap the terminals thereof, whereby the tongue is connected with the flap 8 without gumming and its length 6 extends therefrom in downward direction in the'position 1 shown in the drawings.

. '8 designates a supplemental flap which is connected with the flap '3 and has on its inhesive material as at 9, whereby it may be ner face on the lower portion thereof adsecured to theback 10-of the bodyof the envelop as a fixture thereof while said supplemental flap is secured to the flap proper bythe tongue 5 withoutany gumrning therewhatsoever,allowing said flap proper to be disconnected from the supplemental flap to open the envelop, although the lower portion of said supplemental flap remains connected with the back of the body by the adhesive material employed, as has been stated.

The connection of the flap is as follows In the supplemental flap are transverselyextending parallel openings 11, 12 and 13. This leaves between the openings 18 and 12, the cross bar 14, and between the openings 12 and 11, the cross bar 15. Now the main length 6 of the tongue is reeved through the openings 11, 13 and 12, and, turned up on the upper wall of the opening 13 and over the cross bar 14: and then tucked into the opening 12 whereby its end is beneath the cross bar 15 against the portion of the tongue rearward of the opening 12, thus securely connecting the supplemental flap with the flap proper of the envelop and retaining the tongue in its locked position, preventing improper separation and disconnection of the flaps.

When the envelop receives merchandise or goods the supplemental flap is caused to adhere to the back of the body by the material 9, thus-closing the envelop and retaining its contents reliably therein. Should a post oflice oflicial desire to inspect said contents he manipulates the tongue whereby it may be drawn through the supplemental flap when the flap proper may be opened exposing said contents, but the supplemental flap remains adhering to the body of the envelop so that the flap proper may be returned to its closing position and the tongue restored to the supplemental flap and interlocked therewith, it being noticed that the envelop'and flap are in no wise fractured or injured and so the envelop is available for service to its destination and consequently for re-useif so desired.

While I denominate the device as a mailing envelop it may be used for general business purposes as a package or folder to contain merchandise or goods, and carry or transmit the same in closed condition to its place of destination.

Having thus describedmy invention what I claim as new and desire to secure by Letters Patent, is

In a mailing envelop, a body and a closing'flap proper, a supplemental flap, and a tongue having a T-head, said flap proper having therein an opening, with the wall of which said tongue is interlocked by the head the lower end of said supplemental flap being adapted to be secured to said" body,

andthe upper end remaining free ofjsiaid flapproper, excepting by means of said head of the tongue, said tongue extending from the flap proper and being adapted to be Copies of this patent may be obtained forfiire cents eaq hbj addressing the q oiziiziis eion'er, of intents;
